7+2x)(6+2x) = 45

What is the simplified form of 3 over 4x plus 3 + 21 over 8 x squared plus 26x plus 15
arsen [322]
This is the concept of algebra, we are required to add up the terms given above, here we shall have:
3/(4x)+21/(8x)+26x+15
when we sum up we get:
27/(8x)+26x+15
=(27+208x^2+120x)/(8x)
The simplified form of the summation of the terms is:
(27+208x^2+120x)/(8x)

6. Find the total bill:
daser333 [38]

First multiply all the items up with their correct prices.

5 Golf Clubs = 18.65 each

5 x 18.65 = 93.25

60 Golf Balls = 16.50 per dozen

60 = 5 dozen

5 x 16.50 = 82.5

1 pair of golf shoes = 75.80

1 x 75.80 = 75.80

Now, add them all up.

93.25 + 82.5 + 75.80 = 251.55

Lastly, multiply by 1.15 to add the 15% sales tax.

251.55 x 1.15 = 289.28

Thus, the total cost of all the equipment with tax is $289.28
